Why in news
Scientists using the James Webb Space Telescope (JWST) identified a 'black hole star' (MoM-BH*-1) from the early universe, potentially explaining mysterious red spots in cosmic images.
Background
The object MoM-BH*-1 was observed from a period when the universe was only 660 million years old. It emits 100 billion times more energy than any star and exhibits light-absorption properties characteristic of a black hole surrounded by dense gas.
